Bledsoe for The Hill, “Trump is isolated on climate. Ignore him at negotiations.”

Convincing major-emitting nations to increase the pace of emissions reductions, gaining hundreds of billions in new private and public investment in clean energy, protecting vulnerable populations and finalizing key rules of the Paris Agreement will all be debated.

The backdrop? Increasingly deadly, hugely expensive climate change impacts now manifest in the U.S. and around the world and what scientists believe is a rapidly shrinking window of time to prevent far worse.

Within this urgent context, little effort should be spent worrying about or currying favor with Donald Trump or his appointees. Everything we’ve learned about Trump since he took office suggests it’s a fool’s errand to attempt to convince him to take more responsible action regarding climate change.
